Definitions

  • the invention relates to a method for generating and providing a mobile application according to the preamble of claim 1.
  • mobile applications for the configuration, maintenance and / or diagnosis of data processing devices are provided in a so-called app store and can be downloaded from the app store using a mobile device such as a smartphone.
  • a mobile device such as a smartphone.
  • this assumes that the user of the mobile device is registered in the app store and has authorization to download the mobile application.
  • this method is problematic in that the user can load a device-specific mobile application intended for the data processing device from the app store, but it is not ensured that the loaded version actually matches the current firmware of the data processing device to be processed. In the worst case, the user cannot use the mobile application loaded onto his mobile device with the data processing device without updating the firmware or downgrading the mobile application.
  • the present invention is based on the object of developing a method of the type mentioned at the beginning in such a way that the provision of a current device-specific mobile application for the configuration, maintenance and diagnosis of a data processing device is simplified.
  • the object is achieved by a method having the features of claim 1.
  • the mobile application is hosted in the data processing device and can be loaded directly from the data processing device by the user.

  • the hosting data processing device is designed to update or change the content or the functions of the hosted mobile application based on current data of the configuration and the runtime environment of the hosting data processing device.
  • the generation logic is designed to acquire data of a configuration and / or a runtime environment from further data processing devices coupled to the hosting data processing device via a network and on the basis of the data of the hosting data processing device and the acquired data of the other Data processing devices to generate or update the mobile application.
  • This procedure provides a mobile application on the mobile device that can interact with a large number of data processing devices connected to the host data processing device via a network.
  • the mobile application is enriched with data that is dynamically recorded by the other data processing devices.
  • the mobile application is updated dynamically with current information / data from the various data processing devices at the time of installation or at the time of provision.
  • Both the hosting data processing device and the other data processing devices connected to the hosting data processing device via the network are data sources for the mobile application installed on the mobile device.
  • the mobile application is provided in the form of a progressive web application (PWA).
  • PWA Progressive Web Application
  • the concept of the Progressive Web Application (PWA) is used as an exemplary, but preferred, technology for realizing the invention. Regardless, the invention can be implemented and carried out using various technologies and communication protocols.
  • the generation of the application data of the Progressive Web Application (PWA) is initiated when the mobile device and the hosting data processing device are coupled for the first time and that the update of the application data of the Progressive Web Application (PWA) is initiated with each subsequent connection and only one data update is sent to the mobile device.
  • a unique identifier ID is generated using a MAC address of a web server of the hosting data processing device and implemented in the progressive web application (PWA).
  • an index.html is requested during a first connection between the mobile device and a data processing device hosting the Progressive Web Application (PWA), by means of which a ServiceWorker is registered and that the ServiceWorker is loaded into the mobile device and is installed and activated on the mobile device.
  • PWA Progressive Web Application
  • the data processing device such. B. an IIOT device

  • a progressive Web Application is generated with the latest data available on the data processing device the user is connected to with his mobile device.
  • the content / data of the progressive web application come from only one device.
  • the data processing device has a connection to other data processing devices in the same environment, diagnostic / maintenance data can be acquired from these devices during the generation phase. This results in an updated application that consists of all available data from all connected computing devices in the environment.
  • the content of the Progressive Web Application comes from several data processing devices.
  • the installed application is a backbone that can interact with multiple computing devices such as IIOT devices in the environment and dynamically improve itself with data captured by other computing devices such as IIOT devices. As a result, an update with the latest information from various computing devices such as IIOT devices is carried out at installation / provisioning time.

Another advantage is that registration with an app store is not necessary.
  • the data processing device D1 is designed to generate the mobile application MAPP and to update it during operation in order to map changes to configuration data or data of a runtime environment of the data processing device D1. Consequently, the data processing device D1 acts as a data source for the hosted mobile application, so that the mobile application MAPP is always up-to-date at the time of installation or at the time of provision.

  • the mobile device MD has at least one web client WC and a web browser WB, via which the web server WS of the data processing device D1 can be called up by means of the communication connection KV.
  • a Progressive Web Application PWA is a website that has numerous features that were previously reserved for native apps. It can therefore also be described as a symbiosis of a responsive website and an app.
  • the progressive web application PWA can be created like a website with HTML 5, CSS 3 and JavaScript;
  • so-called ServiceWorker SW are used for optimized caching of offline functionalities.
  • the HTTPS protocol can be used for communication between a web client WC of the mobile device MD and a web server WS of the data processing device D1, z. B. the HTTPS protocol can be used.
  • the progressive web application PWA is started by z. B. a URL of the web server WS entered in the web browser WB of the mobile device MD and thus a first request is sent.
  • the web server WS receives the request and forwards it to the PWA, which functions as a web application. This generates or loads an HTML source code for a website, which is sent back to the browser by the web server (HTTPS response).
  • the user sees a website that is adapted to the mobile device due to its responsive design.
  • the progressive web application PWA was accessed via a URL, the user can see an icon on the screen of the mobile device such as smartphone or receive push notifications and can also use the page offline.
  • the technology based on progressive enhancement is intended to offer users the best possible user experience, depending on the devices used.
  • a ServiceWorker SW is a JavaScript which the web browser WB executes in the background. It provides essential PWA functions for progressive web applications such as caching for offline use. Once accessed online, content can be displayed the next time you visit the site even without an internet connection (offline mode). Push notifications known from native apps are also possible with ServiceWorkern SW.
  • the ServiceWorker SW are specially programmed, registered and installed in the JavaScript of the site. ServiceWorker SW operate HTTPS, which is why every Progressive Web App runs with HTTPS. A connection via an unsecured HTTP connection is not possible.
